Raw power and blazing speed coupled with great coverage make this set extremely dangerous

will almost always get at least one kill

won't usually be able to sweep, but excels at blasting holes in teams, easily being able to get 1-2 kills if used at the correct time

Psystrike was a great gift for Mewtwo, allowing it to power through Chansey and Blissey (and to a lesser extent Kyogre and Ho-Oh) without Selfdestruct

Ice Beam hits the multitude of Dragon-types hard and is a great attacking type because it can hit Giratina/Lugia/Groudon for super effective damage

The choice between Fire Blast and Aura Sphere in the third slot can be a difficult one. Fire Blast is dependent on the weather either being neutral or sunny to be able to hurt Jirachi, Metagross, and Bronzong. Jirachi is notable because it is the closest thing to a Mewtwo "counter" there is outside of sun. Aura Sphere hurts Tyranitar, Heatran, Dialga, and Dark Arceus on the other hand.

The last slot has some options too. If you want more power, Mewtwo easily finds opportunities to use Calm Mind with its offensive presence. If you don't want to choose between Aura Sphere and Fire Blast, you can simply use both, forgoing Calm Mind in favor of less power but better coverage.

EVs are obvious

Timid is necessary to outspeed Pokemon such as Darkrai, Arceus, and Shaymin-S

[Additional Comments]

Substitute can be used to take advantage of the switching Mewtwo is bound to cause. The answer to Mewtwo is usually sacrifice something then switch out a revenge killer: Substitute capitalizes on this.

Mewtwo has tons of coverage options, but the ones listed are usually ideal

Thunderbolt can be used as well but generally considered inferior - Mewtwo really enjoys the extra power Thunder provides

Shadow Ball can be used to hit Pokemon such as Giratina, Latias, and Lugia . It also hits Wobbuffet hard, but it should be noted that Wobbuffet has 0% chance to be OHKOed by even +1 Shadow Ball after Stealth Rock. Also, even super effective Shadow Ball is outdamaged by neutral Fire Blast in the sun (by a considerable amount)

Flamethrower is there for reliability and more PP, but Mewtwo really needs that extra power

If you are using Fire Blast, Groudon is a good teammate to provide sunlight

Without Aura Sphere, Tyranitar, Heatran, Dialga, and Dark Arceus in the rain can all give Mewtwo some trouble. All three of four Pokemon are weak to Fighting-type attacks, so something like Fighting Arceus (which can easily take a hit from each of these Pokemon bar a Specs variant of Dialga) works well. Ground Arceus can also work for three out of the four, but besides those two there are few Ground- or Fighting-types that don't mind the attacks those four can throw at them.

Jirachi, Psychic Arceus, Metagross, Bronzong can annoy Mewtwo if it lacks Fire Blast or its raining. Groudon with Fire Punch and Earthquake can handle the three Steel-types (Jirachi being really the only one commonly used), where as Psychic Arceus is rarely used, but can be destroyed by Darkrai.

Mewtwo is often relying on raw power to muscle through Pokemon, so entry hazards go a long way to aid Mewtwo smashing through teams. A Pokemon to lay them down is good (Forretress, Tentacruel again + Ferrothorn, Skarmory, Deoxys-S). SR + SPikes with either Shadow Ball or sunshine with Fire Blast is needed to ensure Wobbuffet doesn't counter Mewtwo even with +1 SpA, although mind games can be played with Calm Mind / attacking move + Encore/Mirror Coat

One really shouldn't try to support Mewtwo with defensive synergy as people will rarely try to take out Mewtwo via super effective coverage, rather strong neutral attacks or status.

People often rely on revenge killers to take Mewtwo out after it has taken a few rounds of Life Orb recoil, so something like lure Thunder Wave Kyogre can help out (be careful if using Fire Blast + Kyogre)

Very few Pokemon can actually outright OHKO full HP Mewtwo with the movesets they commonly run, so be careful with your Life Orb recoil and prediction!

Leftovers can be used to take advantage of this, but the power drop hurts

Wobbuffet can be used to eliminate a Choiced revenge killer and open up a sweep for another Pokemon. Unfortunately, it has the same weaknesses as Mewtwo, but people rarely try to exploit Mewtwo's weaknesses to take it down. Rather, they rely on strong neutral attacks.

Ok so the set on site has some major slashing issues. I really don't know how to fix this. Throwing all the support moves into slot 4 with a mention of how you can swap out coverage for support moves makes it look too much like Psycho Killer, while Calm Mind / Substitute / Recover are all fairly good and hard to choose between. I also really think this set is a bit of wasted potential without the ability to set up, as without that you may as well just mention a bulkier spread in Psycho Killer. Also, without Ice Beam, this is just set up bait for Latias :/ (nvm)Input needed

This set aims to use Mewtwo's bulk and utility movepool to set up while staying relatively healthy, then proceed to SMASH

Gives up the power to simply smash and tear holes for the ability to set up Calm Mind more reliably

"Bulky Attacker" may seem to indicate this is inferior and wasting potential on such a powerful attacker, but this set is actually more likely to pull off a sweep and focuses on that rather than blasting holes

Mewtwo's bulk is often overlooked and is not too shabby

Takes advantage of the sacrifice something and revenge kill mentality a lot of players use when facing Mewtwo

Psystrike is basically manditory on Mewtwo as a powerful STAB move that destroys Chansey/Blissey

the choice between Fire Blast / Aura Sphere depends on what you want to hit harder: Steel-types such as Jirachi Metagross and Bronzong (as well as being extremely powerful against Pokemon that resist Psychic that are neutral to Fire in the sun), or Pokemon like Dialga, Heatran, and Tyranitar.

Calm Mind is extremely useful to assist in sweeping

Ice Beam is useful for additional coverage against Dragons

Recover is useful to heal off damage taken while setting up. After a Calm Mind use, many Pokemon are unable to do more than chip away at Mewtwo's health, allowing it to get a few Calm Minds before they realize their efforts to chip away are in vain as Mewtwo uses Recover.

Timid is still necessary to outspeed Arceus and Darkrai

100 SpA EVs ensure Psystrike can 2HKO 52 HP Latias after Stealth Rock, forcing it to either spam Recover, allowing you to get another Calm Mind, or die

Leftovers goes a long way and Life Orb is far too detrimental to the purpose of this set

[Additional Comments]

Mewtwo has major four moveslot syndrome

Taunt is also an option to help Mewtwo set up against slower-paced teams

You can invest more in bulk or more in SpA depending on how bulky/powerful you want Mewtwo to be

Substitute is useful for preventing status and scouting counters. With 204 HP EVs, Mewtwo can make 101 HP substitutes which require 2 uses of Seismic Toss to break. Mewtwo can easily set up a Substitute on a lot of Dragon-types after they have used Draco Meteor. Coincidentally, 52 SpA EVs (how much will be left over) are enough to ensure Latias will be 2HKOed by Ice Beam even if it uses Calm Mind assuming it switches into Mewtwo using Calm Mind with Stealth Rock on the field.

There are quite a few combinations of utility/coverage moves that you can tailor for your team

More coverage moves means Mewtwo will be walled by less Pokemon, but also means it will (generally) have less potential to set up and sweep

If you don't really care about the extra power and would prefer a little extra bulk, you can move the SpA EVs into HP

Conversely, running max SpA is also an option if you want to hit harder, but doing this kind of goes against the idea of this set

This Mewtwo appreciated a bit more support than the all-out offensive variant

Toxic Spikes basically neuter this variant of Mewtwo, so something to absorb or spin them away is necessary (Tentacruel, Poison Arceus, Forretress, Excadrill)

Without Ice Beam, Lugia in the rain (or in any weather if you lack Fire Blast too), Latias, and to a lesser extent Giratina can wall you all day. Darkrai, Ghost Arceus, and Dark Arceus can all help against these Pokemon.

Without Aura Sphere Dialga, Tyranitar, Dark Arceus in the rain, and Heatran can give Mewtwo some problems. Fighting Arceus is a good choice that can take a hit from all of these Pokemon and strike back with super effective STAB. Ground Arceus also deserves a mention for being able to take 3/4 of the Pokemon on.

Without Fire Blast, Jirachi, Bronzong, and Metagross can attempt to wall you, but, depending on what they are running, they may not be able to do much back. Jirachi can't always break Mewtwo's substitutes with Iron Head, Metagross does around the same damage to Mewtwo as Mewtwo does back with +1 Aura Sphere, and is always outsped even if it is holding a Scarf. Bronzong does fairly well, but is rarely seen in Ubers.

Without Calm Mind, you fail to break through Pokemon such as Chansey

Forgoing Substitute gives up the ability to scout incoming switches and makes Mewtwo vulnerable to things such as Thunder Wave Dialga and Toxic Jirachi

Without Recover, you have a lot less staying ability

Groudon can provide Stealth Rock and power up Mewtwo's Fire Blast

Mewtwo can't really create defensive cores with this set, so one should focus on offensive synergy rather than defensive. Pokemon like Darkrai (which can eliminate most problematic Calm Mind users that Mewtwo has trouble with) and Fighting Arceus make good partners

Seems rather weird, but is extremely effective, especially against opposing stall teams

Mewtwo's great Speed and support movepool let it stall out and annoy a wide variety of threats. Pressure helps too.

Taunt allows Mewtwo to prevent other Pokemon from statusing it, healing themselves, or setting up

Recover in conjunction with Mewtwo's Speed allows it to heal before most things can even touch it

Once again, 4 moveslot syndrome kicks in for slots 3 and 4

Will-O-Wisp allows Mewtwo to stall out non-Fire-type physical attacks quite effectively, letting it repeatedly heal while they slowly die to burn damage. Toxic does more damage faster with the downside of leaving Mewtwo helpless against Steel-types and without a way to cushion the blows of powerhouses such as Zekrom and Groudon

Psystrike allows Mewtwo to hit Ho-Oh and Reshiram hard if you are running Will-O-Wisp, as otherwise Mewtwo would have no way of touching them

Light Screen lets Mewtwo sponge the hits of powerful special attackers with ease, and makes Mewtwo fairly hard to crack when used with Will-O-Wisp

Substitute is useful for scouting a switch in, and preventing status. It also helps Mewtwo stall out the numerous moves with 8 PP, thanks to Pressure.

The given EVs maximize bulk while still allowing it to outspeed Arceus

EVs are definitely not set in stone as Mewtwo has a variety of viable EV spread. You can run enough to outspeed Darkrai (216 EVs with a neutral nature, though Mewtwo can't do much back), or, if outspeeding Arceus doesn't bother you, drop it down to enough to outspeed base 110 Speed Pokemon such as Latias, Latios, and Lugia (96 EVs with +Speed or 220 EVs with neutral nature). These three are a handy benchmark, but you can drop Mewtwo's speed down still further to enough to outspeed base 95s, namely Rayquaza, if that all you really care about (88 EVs with neutral nature).

Where you move the EVs to is really up to you. Mewtwo can go physically or specially defensive, and you can even shift the SpD EVs to Def.

The best way to determine your EV spread is to open up a damage calc and determine what is most important for Mewtwo to survive for its purpose on your team, because there's just so many options

With Will-O-Wisp you have to stall for more turns (risking crit, 10% chance moves etc) than Toxic, but with Toxic physical attackers give you trouble.

Without Light Screen, powerful special attacker can demolish Mewtwo, though, given, not many like taking even an uninvested Psystrike (252 HP Kyogre has a good chance to be 2HKOed after Stealth Rock). Chansey or Blissey can easily sponge special attacks if you forgo Light Screen.

One of the great things about this Mewtwo is that it completely rewrites the list of Pokemon that can check/counter it. Defensive or bulky Pokemon hoping to tank a hit from Mewtwo and cripple it through non-attacking methods now are easily neutered and offense is the easiest way to break through it

Darkrai, Ho-Oh, and Reshiram are the biggest enemies to this set if Mewtwo is running Will-O-Wisp. Darkrai doesn't really care about anything Mewtwo can run besides Toxic and can smash it with Dark Pulse or sleep it with Dark Void. Ho-Oh and Reshiram don't really appreciate Psystrike, but can wall Mewtwo to no end if it lacks both Psystrike and Toxic. These are two Pokemon you do not want to give a free switch in to, so Stealth Rock support and something to deal with them is helpful if you forgo both of these moves. Kyogre can take Fire-type attacks from both but has to watch out for their other STAB. Kyogre can also take care of Darkrai provided that Sleep Clause is activated and Dark Pulse doesn't flinch.

Toxic Spikes completely neuter this Mewtwo set, so a spinner or absorber (Forretress, Tentacruel, Excadrill, Poison Arceus) is almost mandatory.

Tspikes support may contradict the use of Will-O-Wisp, but they are notable for allowing Mewtwo to simply Taunt and begin spamming Recover without having to waste a turn (and take damage) statusing something.

Appreciates hazard support for the switching it will cause

Xatu shuts this set down

[Other Options]

Physical sets? (bulk up)

Expert Belt I guess

It does have a massive movepool

Dual Screens + Selfdestruct + Taunt

Choice sets suck

Defense boosting moves

[Checks and Counters]

It does not have any failsafe counters. Ever.

One must be careful because checks to offensive Mewtwo often fall flat against a support variant or even a more defensively-oriented offensive set

defensive Dark Arceus with Payback is a bit gimmicky but is probably one of the closest things to a "counter" offensive Mewtwo has, but will actually lose to stalltwo

Jirachi can check offensive variants in the rain or in neutral weather if they lack Fire Blast. +1 Aura Sphere fails to 2HKO, but Fire Blast still can unfortunately. However, Jirachi will still have an opportunity to Poison/Paralyze Mewtwo, effectively neutering it.

In a similar vein, Metagross and Bronzong can be used for a more offensive and less defensive check in the rain/if Mewtwo lacks Fire Blast

Without Life Orb and Calm Mind, Chansey has a respectable chance to live 2 Psystrikes, but don't count on it because any Mewtwo without Life Orb will most likely have either Calm Mind or Substitute.

Wobbuffet can very effectively check non-Taunt variants, as even +1 Shadow Ball will never OHKO 28/252+ Wobbuffet after Stealth Rock. +1 Fire Blast in the sun, however, has a decent chance (a little over 50%) to OHKO Wobbuffet after Stealth Rock

Be wary of going straight to revenge killers though, as few things outright KO full HP Mewtwo, so hazards and abuse of Life Orb recoil via prediction are often useful before the revenge killer comes in

That being said, almost every user of Choice Scarf can revenge kill Mewtwo after some prior damage. Physical ones such as Zekrom, Garchomp, and Terrakion are notable for being able to revenge kill Mewtwo regardless of how many Calm Minds it has obtained

Specially based Choice Scarf users must be careful not to let Mewtwo obtain too many Calm Minds

Toxic Spikes and the fact that Mewtwo commonly carries Life Orb can help wear it don quickly

Giratina-O can make a dent in Mewtwo with Shadow Sneak, but Ice Beam does major damage back

Ghost Arceus can take a hit and OHKO Mewtwo with Judgment provided it hasn't used Calm Mind. If it has +1 SpD, Arceus needs a good deal of prior damage to ensure the KO with Judgment

Victini resists all of Mewtwo's commonly used moves and can OHKO with V-create in the sun. Despite it resisting, Mewtwo can still 2HKO it after Stealth Rock so it has to be careful

If you can keep Stealth Rock off the field (which is oftentimes easier said than done), Multiscale Lugia can attempt to check Mewtwo with Thunder Wave or Toxic in combination with Roost. Or just flat out spamming Roost to kill Mewtwo with Life Orb recoil (won't work if Mewtwo has Calm Mind or Taunt), and only against offensive variants

For stalltwo, powerful special attackers (such as Kyogre and Reshiram) are good choices.

Ho-Oh and Reshiram are immune to WoW from Stalltwo, but both take a beating from Psystrike. They can effectively force it out (or KO it) in most cases though

Why doesnt victini get a mention in checks/counters? It resists all of Mewtwo's common moves(Shadow Ball is almost never used) and can OHKO with V-Create under sun. Now for damage calculations:
252SpAtk Life Orb Unnerve Mewtwo (Neutral) Psystrike vs 4HP/0Def Victini (Neutral): 35% - 41% (120 - 141 HP). Guaranteed 3HKO.

Mewtwo's strongest attack in neutral weather against Victini is only a 3hko.

I forgot Victini because it is rarely ever seen lol. I'll add it in. To be honest I didn't mention Lugia because it isn't that reliable. I mean, its has a very strong chance to be OHKOed after Stealth Rock from +1 Mewtwo (with 252/0 at least). Even with Thunder Wave, you have to hope that it gets full para when you use it. That and or low damage rolls is the only scenario in which your Lugia lives with Stealth Rock up. I'll throw in a mention of Multiscale Lugia with SR off the field though I guess. Giratina is in a similar boat. It isn't 2HKOed by non-boosted Ice Beam, but it can't really do anything to Mewtwo.

Ok so the set on site has some major slashing issues. I really don't know how to fix this. Throwing all the support moves into slot 4 with a mention of how you can swap out coverage for support moves makes it look too much like Psycho Killer, while Calm Mind / Substitute / Recover are all fairly good and hard to choose between. I also really think this set is a bit of wasted potential without the ability to set up, as without that you may as well just mention a bulkier spread in Psycho Killer. Also, without Ice Beam, this is just set up bait for Latias :/Input needed

Click to expand...

Actually Latias can't set up on it due to +1 Psystrike 2HKOing O_O, yes Latias is WEAK.

Also can recover be slashed into the 4th slot of Psycho Killer, its been tested to be effective but I don't know if that destroys the point of there being a bulky attacker set since it was supposed to reduce the slashitis.

I'm also a bit concerned about bulky attacker being an inferior Latias, seeing as Latias has levitate to avoid spikes + tspikes, refresh to beat Blissey, and the ability to double as a Specs Ogre switch-in, but 101 subs and a legit movepool (fire blast, ice beam, aura sphere) is pretty huge so I DONT KNOW.

Something to put about stall 2 in its set comments is that its extremely easy to phaze out. Anything that uses Dragon Tail can just lol really and then you have the chance to setup tspikes or hazards or something... Also Xatu in AC for partner for Stall 2 for bouncing back hazards :D, also its worst enemy since it lols at Psystrike and can make it Taunt itself for more trolling. The type stacking is weird though. Stall 2 also appreciates hazards to hasten the death of the other team, needs a mention about being a good quick stall member too IMO.

First off the 1st set last slot looks really terrible imo and the moves look oddly paired. Why does Substitute get a slash at all on Psycho Killer, it should be relegated to AC imo. Ideally IMO, Psycho Killer should look like this,

Ice Beam shouldn't have a slot of its own and should be slashed with Fire Blast since its arguably more useful on sun teams and turns a lot of partial Mewtwo checks into non checks. Aura Sphere needs to be there so that Mewtwo can take on Steels especially Dialga and Steelceus. On the last slot Calm Mind is for the buff to the offense and special defense while Recover can be really really good for healing on the forced switch, poppy introduced me to this set and its actually great.

Yeah i have to agree with firecape, i dont get the point of bulky mewtwo. What exactly is it accomplishing ? 204 HP is no great benchmark anyway. Like shrang said on irc, 101 HP is so DPP. What exactly is going to take on Mewtwo with Seismic Toss, that isnt defeated by Psycho Killer anyway. Stuff like Chansey shouldnt even take on Mewtwo in the first place. I frankly think this set should be scrapped and be dumped into OO or if you're feeling generous into Psycho Killer AC. Not to mention 52 SpA is just too weak, you're not even realiably 2HKOing other Mewtwo without Sun -_-

You should probably mention on Stalltwo that its no longer as good as it was in gen 4 since Dragon Tail is here like Mr LOL said. It can no longer clamp down on Tina like it used to earlier but I guess its barely viable. Rest looks fine. I'll wait a bit for feedback from you before approving it :p

Just scrap Substitute off from Psycho Killer. Mewtwo can just smash Ferrothorn with Fire Blast regardless of weather. There's no way Ferrothorn can wall Mewtwo.

I actually agree with firecape on the Ice Beam slashes. Ice Beam is really important because it hits Giratina and Lugia harder than any other move. It's your only way to 2HKO Giratina directly(after SR for better chances) without any boosts and destroy Lugia at least some of the time. Getting walled by Lugia outside of sun isn't fun at all.

StallTwo is still fine when I used it. If you are mentioning Victini, you might as well mention Cresselia too. Without Fire Blast, Cresselia can come in and paralyze/toxic you, set up Light Screen, Moonlight off the damage and do nothing else.

Agreeing with barry. Bulky Mewtwo is a waste of its sweeping potential. Without much Special Attack EVs and Calm Mind, Mewtwo is pretty weak. Even physically defensive Ho-Oh walls you.

firecape is strong and I trust him more than anyone here :)QC APPROVED 1/3

I dont really get the point of Ice Beam being a move with slashes. It hits most of the Dragons in the tier for supereffective damage. Without Ice Beam, Zekrom can take a hit and hit it back. Lugia and Giratina and Giratina-O and even Groudon, to an extent, can prove to be even more problematic. Fire Blast needs a slash with Aura Sphere and just a mention that Mewtwo should use Fire Blast if it has Drought support since a Sun-Boosted Fire Blast is as strong as a supereffective Aura Sphere. So, the point about hitting Dialga and Steel-Arceus with Aura Sphere is not that important. Also if Mewtwo is used in a sun team then it will have very little use for Aura Sphere since all that it needs to hit will be dealt the same damage from sun-boosted Fire Blast.
EDIT: Ninja'd

Aura Sphere is definitely a more important move than Ice Beam, IMO, while Fire Blast and Ice Beam are interchangeable, depending on the team you're running. I personally hate Mewtwo that can't beat Scizor, which actually look like it might see a rise with Soul Dew Lati@s making a return as well as the new Kyurem forms. Aura Sphere gives you the best general coverage alongside Psystrike, while allowing you to revenge-kill Darkrai pretty much whenever you want. Tyranitar is also common enough to warrant the use of Aura Sphere on all sets. With Fire Blast and sun support, Mewtwo literally has no counters whatsoever, while Ice Beam gives general reliability in the rain. I personally like Fire Blast better because it is more dangerous. As for the last slot, Calm Mind / Recover look like the best options, but make a strong emphasis in AC that you are at perfect liberty to run that other coverage move.

On another note, I do think Choice Scarf Mewtwo should be given a shot. Like I've said in pretty much every Mewtwo analysis so far, it may seem crappy looking simply because Psycho Killer is so good, Scarf Mewtwo is still quite a nice revenge killer if you need one. 591 base Speed is outspeeding stuff like Adamant Excadrill, +2 Blaziken, and a whole host of speed boosters. It also has the coverage to take down pretty much all of them, as well as Trick to fuck walls up. It's definitely worth looking into, IMO:

I'm not lazy I just wanted to switch just in case TrollFreak wanted to do an analysis still. Kyurem-B write-up will likely be worked on tomorrow afternoon but meh.

Anyway, Psycho Killer looks really slashy and we should probably cover what is necessary amd what is not. I think all of us, especially Cold_Eye, can agree Psystrike is a must on the set. It seems like the disagreement starts right at slot 2...

I want to emphasize that I really think Ice Beam is kmportant. It hits the Lati twins, Giratinas, and Lugia. Also aside from weather conditions and Aura Sphere, it is one of Mewtwo's better moves against Dialga. Ice Beam also strikes Dragon Arceus, for what ots worth.

The next slot is when it gets tricky. I really think, especially with Groudon support, Fire Blast is probably your next best attack. With the sun its like a psuedo-STAB and doesn't get trolled as hard by Chople Darkrai. Also, with the possibility of Scizor returning to hamper the Lati twins, its a crucial attack to carry. Aura Sphere should be slashed with it for rainy conditions that Mewtwo might encounter.

Slot 4 should probably the hardest one for me because I always think I should use Grass Knot or Thunder to hit Kyogre (and Thunder is slightly better versus Lugia in the rain). Calm Mind always seems like an afterthought to me, but this might be because I kind of play Psycho Killer like a revenge killer before sweeper.

why is it even called psycho killer? nothing differentiates it from the bulky attacker, not psystrike, not calm mind, except its offensive nature. i understand if it's some sort informal standard, but logically it should juts be called 'offensive'

anyway,

Psystrike
Ice Beam
Aura Sphere / Fire Blast
Calm Mind / Recover

IMO. Ice Beam should always be used because it hits so many things super effectively.

Moderator

Honestly, Calm Mind/Recover on the last slot doesn't feel right to me. This is because 4 attack Mewtwo is perfectly viable (by that I mean really good), and allows Mewtwo to abuse its coverage. Something like

On the bulky Attacker, why is Fire Blast listed before Aura Sphere? Getting past Dialga and Tyranitar is HUGE. Jirachi, Bronzong, and Metagross are uncommon anyway. I also want a Substitute slash somewhere, as SubCM is a perfectly viable set. Probably on the last slot, after Ice Beam.

Why is that? You should list every Pokemon that is capable of beating the Pokemon you're writing about, and that is viable in the metagame you're writing for. Thus, add Dark Arceus, Psychic Arceus, and Scarf Kyurem-B. Forretress can do some damage with its Gyro Ball, and only fears Fire Blast. And yeah, do mention Specially Defensive Giratina.

If you want to put holes in people, you want four attacking moves. If you want to attempt some sort of (mini)sweep, you should use better coverage moves. With stealth rock on the field, the vast majority of things are OHKOed by psystrike, ice beam, or aura sphere. Calm Mind and fire blast doesn't do very much for coverage, your sweep will be stopped by ttar or dialga. The only common pokemon to take the three coverage moves I suggest is forretress, who still takes like 70% from aura sphere. Recover could be used to preserve mewtwo. It is a very dangerous pokemon and if preserved can stick around to inflict more damage. Taunt would be used primarily if mewtwo was used as a lead, to prevent hazards.

Bottom line: If you want to attack right away you use fire blast. If you want to set up and sweep you use calm mind. Taunt and recover are other niche options, and could even be put in AC or OO, or whatever section they belong in.
